1. On the phase (when you initially solder) how do you take into account the polarities shown on the boards . It is not clear neither in the video nor in the instructions.
    Can you please help me?

  2. The Funduino board has six pins : GND, CTS, 5V, TXD, RXD and DTR and the keystudio board has five pins RST, VCC, RXD, TXD and GND. Can you give me which pin is connected to what?

  3. How do you use the usb loader to upload programs from the Cube4 library. It seems to not work.

    1. The LED cube cannot be directly connected to the computer. Please refer to the WIKI link below the video for details.

  4. Hi,
    I put the cube together, but I cannot figure out how to program the cube. I wired it up to the chip they supplied and connected it to my computer but I cannot get the arduino ide to recognize the chip.

    getting this error message when I try to program

    avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x20
    avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x30

    Do you have any advice? Please help, thanks!

    1. Hello, you need to check whether the corresponding drivers and code base files are installed. In addition, you need to provide your use process. My side can easily solve the problem.
      You can refer to the WIKI link at the bottom of the video first.
